So I got my FC660C in today & have been using it for a couple hrs now. This is my 1st experience with Topre ever & I can see now why some people swear by them. The smoothness of these switches is next level even in their stock form, definitely the biggest & most noticeable improvement over other switches for Topre IMO. The stock 45g domes this board comes with feel pretty good, but a bit light for me. They are very tactile but in a sneaky way, if that makes any sense. The tactile bump is literally right at the beginning of the key press making them have more of a linear feel compared to tactile MX switches.
The board itself is very well built & a little heftier than I expected. It's definitely heavier than it's MX brethren the FC660M. I believe these boards have a steel plate in them so I'd imagine that's where the extra weight comes from. The case is very nice for a plastic case & there is no flex to mention with this KB. As far as the build quality goes it's Leopold's usual top notch stuff, although the option for an alum case for these would be awesome. I heard Norbauer might be making some, fingers crossed there.
Really the only major complaint I can level at this board & Topre switches by extension is that the stabilized keys other than the space bar rattle like crazy! I guess it's really not that bad, but for me coming from my custom MX builds with dead quiet stabilizers it really does bother me. Although I also figure it's nothing some lube & silencing rings can't fix so it's not a deal breaker to me. All in all I'm pretty happy with the Topre experience. They are very unique feeling switch & I'm pretty excited to start messing around with modding them.
I have a batch of BKE redux extreme domes & silencing rings on the way. I also ordered some EK Mechlube 2 but EliteKBs said it won't be in till sometime next month, so I'm probably gonna just use my personal thick mix of Krytox to lube this board. I like the feeling of stock 45g domes, but ideally I'd prefer the feel stiffer & heavier. I was figuring this would be the case going in so I ordered the BKEs the same time I ordered this board. Hoping the BKEs, silencing rings, & lubing will give the board a feel more suited for my preferences & get rid of that damned rattle from the stabilized keys. I could see it becoming one of my more used boards if it all works as planned.
